如何在ubuntu 14.04 LTS上安裝pip？ 安裝時出現此錯誤

Question

我嘗試使用以下命令：

kv@kv:~$ sudo easy_install pip

我收到此錯誤：

Answer 1

從主機到pypi的連接失敗。 這與python或pip或easy_install無關。 您嘗試做的是正確的。

在您重新安裝之前，必須先解決網絡問題。

為了更快地進行檢查，您可以只curl https://pypi.python.org/simple/pip/ 。 獲得返回的文件列表后，請再次嘗試easy_install 。

可能是pypi存儲庫也暫時不可用。 如果您可以從該主機訪問google，請稍等片刻，然后重試。

Answer 2

sudo apt-get install python-pip
